the shell. One of the spiral lines just above the suture and one or 

 two of those at the shoulder are stronger than the rest. Between 

 the ribs the revolving lines are roughened by fine Hues of growth. 



The four nuclear whorls (fig. 2a) are evenly rounded and in strong 

 contrast with those that follow them. The first one is very minute, 

 forming a very acute apex ; the surface is finely cancellated by two 

 sets of lines running obliquely in opposite directions. The aperture 

 is elongated and rather broad in the middle ; the outer lip has a deep 

 and broad posterior sinus, below which it projects strongly forward 

 and is regulaily arched to the base of the canal ; the canal is narrow, 

 nearly straight, slightly prolonged ; the columella is straight and 

 tapered, with its inner edge forming a slightly sinuous curve ; the 

 inner lip is smooth and polished, with a thin coat of enamel which 

 extends somewhat forward in a regular curve on the body-whorl. 

 The color is white with a pale grayish tinge, with the exception of 

 the nuclear whorls, which are deep chestnut-brown.

Plate XXXI, figures 3, 3a. 



Shell small, delicate, fusiform, with an elevated and very acute 

 spire and a slightly elongated, straight canal. Whorls angulated 

 and turreted, sculptureil with ribs and revolving lines, which form 

 rows of small, sharp nodules at their intersection around the per- 

 ipliery, and especially at tlie shoulder. Whorls about four, below the 

 nucleus, which is unusually elongated and composed of four pale 

 chestnut-colored whorls, which are finely and regularly cancellated. 

 The apical whorl is very minute and prominent, giving the spire a 

 very acute tip. The nuclear whorls increase rapidly and regu- 

 larly in size, and are regularly rounded. The sculpture j)asses 

 somewhat gradually into that of the next lower whorl, which is 

 distinctly ribbed and carinated, with a single row of sharp tuber- 

 cles around the middle. The lower whorls of the spire have the 

 shoulder at about the middle, and below it two or three raised cin-
